I have made a small unit, from a brushless fan motor used for cooling a computer, it was easy, but was contemplating on building one that was more powerful, ive got the material and wire to wind my own armature and neodenium magnets to give it a very good try, would it be worth my while to upgrade to overkill along with a storage and inverter setup
Unfortunately, the only supplier of negative resistance wire has discontinued the product.
I am New here and I hate to start out answering a question on Bedini's stuff but...
The answer is NO. Not as diagramed
But what thay can do for you after you learn to build a real high voltage one is allow you to keep your batteries conditioned and sulfation free.
At higher voltages once the batteries are conditioned you can then expect to see higher COP's on the capacity of battery as opposed to the total input power. Usually no more than COP of 3.0. But it is a gain.
There are though, far better and cheaper ways to do the same thing. But it can be an eye opener on small scale to show you there are a few thing about enviromental charges and the electro chemical battery we still do not know.
But don't plan on powering a home from it.
If you need further readig Energetic Forums and PES wiki are better place to start. As always though do not believe what you are told, No matter who tells ya, find it for yourself
